1995 JEEP LAREDO

I just did an engine swap on a 95 jeep grand Cherokee Laredo 4.0 straight 6. It runs for an hour then just dies, it has perfect oil and fuel pressure no obd1 or 2 codes come up the engine light doesn't even come on. My question is why is this happening? And what is the solution to fix this problem?
